Help with model type engine etc please

First post hello to all.

Not a total newbie but close. Had a few 2stroke LBs in past just never did much mech work.

Picked up a cast alum deck Duraforce push walk behind mower. Not self propel.

Need to order various parts.
The only numbers left anywhere are on the engine shroud tag:
Family XL4XS.1415AB
Spec no: 98-1397
Disp cc. 141
99-6703
Tag also reads “ this engine conforms to regulations etc. ...for a emissions model year 1999 .....”

So is this a 1998 or 1999?
What engine code would this be F? Not familiar with that yet.
Any all details about this would be most appreciated.

For sure need carb kit, coil, cables, blade
Can’t proceed on the parts order site yet.

I will try to come back and add pics in a reply shortly.


Thx very much!

here are some pics...

Duraforce is a model E.
Sticker indicates model year as 1999... therefore it is a 1999 machine.
At last count I have about 8 of them from various years.
Should be sticker (label) on mower deck indicating model and serial of mower.

Thank you Russ that certainly helps!
